We have had the airbag light come on for the past 3 years always just before the state inspection is due every time we get it fixed they said its a switch or a connector. But this year was the worst ,light came on in April, this time they said it's the airbag wire harness and would cost over 1500. 00 . We got kia to pay for the part,and we would cover the labor. I'm just worried will this happen again. It should be investigated further.
